This jewelry polishing cloth gently cleans, polishes, and protects your treasured pieces. Use the white inner cloth to remove tarnish and dirt from gold, silver, and platinum jewelry, then buff with the outer cloth to restore a high luster. Avoid using this chemically treated cloth on emeralds, ivory, lapis lazuli, amber, coral, opal, pearls, malachite, 24 carat gold, or turquoise to keep your delicate items safe.
